Comprehensive system of self-adapting anti-interference antenna channel

Abstract

The invention discloses a comprehensive system of a self-adapting anti-interference antenna channel, which is capable of effectively reducing the system cost and complexity. The comprehensive system of the self-adapting anti-interference antenna channel is realized through the following technical schemes: a receive channel (2) and a digital signal plate (3) are connected between a power supply (4) and a controller (5) to form a self-adapting anti-interference antenna system; a single-channel electronic change-over switch capable of rapidly switching a plurality of antenna elements of an antenna array is arranged at the input end of the receive channel; the controller transmits the synchronous switch instruction and digital signal string of the electronic change-over switch to the receive channel and a digital signal plate via a RS422 serial port / and converts the instruction, thus realizing the connection of the receive channel and different antenna array elements. According to the comprehensive system, the weight, power consumption and cost of the antenna system can be further reduced; and the complicated program that a traditional multi-channel self-adapting anti-interference antenna carries out the calibration of amplitude and phase on the channel can also be saved, thereby solving the problem on inconsistent amplitude and phase among the channels of multi-channel self-adapting anti-interference antenna in the prior art.

Description

technical field [0001] The invention relates to a multi-channel channel integrated system of an adaptive anti-jamming antenna in the field of anti-jamming communication. Background technique [0002] The adaptive anti-jamming antenna is a kind of spatial filter, which receives signals from multiple channels at the same time, and performs different amplitude and phase weighting on the channels through a specific anti-jamming algorithm to realize the superposition of useful signals and the cancellation of interference signals. When the size of the antenna array is large, the number of corresponding receiving channels and ADC converters will also be large, which will greatly increase the cost and complexity of the system. pointing deviation. The traditional multi-channel adaptive anti-jamming antenna is required by the consistency of channel amplitude and phase, and the amplitude and phase of the channel need to be calibrated before working. Especially, as the working time of ...
